ESP32-S3 based 1.28-inch round touchscreen display supports Arduino programming

Makerfabs “ESP32-S3 Round SPI TFT with Touch 1.28″ is a small ESP32-S3 with a 1.28-inch round color touchscreen display, a microSD card, support for USB and battery power, and two “Mabee” extension connectors. The board joins other ESP32-S3 round display boards such as the Lilygo T-RGB board or Seeed Studio’s Round Display for XIAO, but with a thinner design, and a square PCB with trimmed corners instead of a round PCB like the other two. ESP32-S3 Round SPI TFT with Touch 1.28″ (E32S3128GC) specifications: Wireless MCU – Espressif Systems ESP32-S3R8 dual-core Tensilica LX7 microcontroller @ 240 MHz with vector extension, 512KB SRAM, 8MB PSRAM, Wi-Fi 4 & Bluetooth 5.0 dual-mode (Classic + BLE) connectivity Flash – 128 Mbit (16MB) W25Q128JV SPI flash, microSD card slot Display – 1.28-inch round LCD with 240×240 resolution (GC9A01 SPI driver), touchscreen controller (CST816S) USB – 1x USB Type-C port Expansion 1x 4-pin Mabee I2C […]

LOLIN C3 Pico is a tiny ESP32-C3 board with battery charging support

LOLIN C3 Pico is a tiny (25.4×25.4mm) ESP32-C3 RISC-V board with 2.4 GHz WiFi and Bluetooth Low Energy connectivity, a few I/Os, and LiPo battery support including charging circuitry. I tend to like Wemos/LOLIN boards, because of their small form factor, support for equally tiny shields, and low price. The LOLIN C3 Pico is no exception, and even adds a few features such as an RGB LED, an I2C connector, and support for battery power and charging. LOLIN C3 Pico specifications: SoC – Espressif Systems ESP32-C3FH4 single-core 32-bit RISC-V (RV32IMC) microcontroller up to 160 MHz with 400 KB SRAM, 4MB Flash Connectivity – 2.4 GHz WiFi 4 and Bluetooth 5.0 LE (in SoC) Expansion headers 2x 8-pin headers with up to 12x GPIO, ADC, I2C, SPI, UART (3.3V I/O voltage) LOLIN I2C port USB – 1x Type-C USB for 5V power and programming Misc – Reset button and user button, […]

Using SenseCraft firmware for no-code programming on Wio Terminal

In the conclusion of our SenseCAP K1100 Sensor Prototype kit review with LoRaWAN and Vision AI, the author suggested that it would be great if SeeedStudio could develop a new firmware that can connect without coding instead of using Arduino programming: I had to rely on my knowledge and experience with LoRaWAN to transmit data wirelessly over long distances. That’s because LoRaWAN has a more complicated connection process than Wi-Fi or Bluetooth. It would be great if Seeed Studio could develop a new firmware that can connect without any coding It did not take long, as SeeedStudio very recently released the first version of SenseCraft open source smart sensor software for no-code sense, process, and uplink that happens to be compatible with the Wio Terminal part of the SenseCAP K1100 development kit. So let’s test the new SenseCraft firmware together. SenseCraft navigation keys We can use Wio Terminal’s joystick as follows: […]

LilyGO T-HC32 board with the world’s smallest Arm MCU (HC32L110B6) is now available for $9

HC32L110 Arm Cortex-M0+ MCU is found in a minuscule 1.59 x 1.436 mm CSP16 package that should make it the world’s smallest Arm MCU. LilyGO T-HC32 is one of the first boards with the HC32L110B6 microcontroller, and it is now available for $8.98 on Aliexpress including shipping. The board offers really basic features with two buttons, a WS2812 RGB LED, and two-row of ten pins each for GPIOs and power signals, plus a 4-pin header for SWD programming. There’s nothing really special about the board or its price, except for the MCU’s size that’s barely discernable from a discrete component, and much smaller than the 7x7mm ESP32-PICO-D4 system-in-package shown in the photo below for comparison.   LilyGO T-HC32 board specifications: MCU – HDSC HC32L110B6 Arm Cortex-M0+ @ up to 32 MHz with up to 4KB RAM, up to 32KB flash memory Expansion – 2x 10-pin header with GPIO, UART, I2C, […]

Gearbest’s parent company is in “bankruptcy review”

Gearbest parent’s company appears to be in serious financial troubles, with “bankruptcy review” documents filled in Guangdong court for Global Top E-Commerce Co., Ltd, after several years of losses. Gearbest.com is one of the most popular online websites based in China selling to overseas markets. It is owned by Global Top E-Commerce Co. Ltd (previously Shenzhen Globalegrow Electronic Commerce Co. Ltd) and was launched around 2014. At the time, it was all fun and games with a growth strategy meaning they’d send products to anyone with a platform, and here at CNX Software, we got plenty of TV boxes, mini PCs, and 3D printers for review. But eventually, samples dried out as the company switched to focus on profitability, Google started promoting YouTube reviews rather than written reviews, and a new law in Thailand prevented me from importing TV boxes in a time and cost-effective manner. In recent years, I’ve […]
